The move to Hydrogen

A couple of interesting articles on hydrogen. Firstly even the Guardian is not sure how ‘Green’ hydrogen is:

https://www.theguardian.com/commentisfree/2023/aug/27/the-guardian-view-on-hydrogen-hype-its-perhaps-not-as-green-as-you-think

‘Tunisia is one of the driest countries in Africa, and has just suffered three years of drought. Yet the EU sees the country as key to producing “green hydrogen” for export to Europe. The trouble is, this fuel is obtained by splitting water into oxygen and hydrogen with electricity generated by renewable sources. Tunisia has lots of sun but precious little fresh water.’

‘Producing green hydrogen in Europe is not impossible. But it is expensive compared with fossil fuels, with even wind-based generation needing larger subsidies. Without big government support packages, it remains an open question whether European consumers would be prepared to foot the very significant price rises needed to go green in this way.’

One again the solution is government (consumer) subsidies.

 

The next one via the Engineer is looking at the requirements to convert Europe to hydrogen:

https://www.theengineer.co.uk/content/news/new-paper-recommends-strategy-to-deliver-renewable-hydrogen

‘According to the report, 25 projects at a scale of 3GW electrolyser and 400KTPA need to be operating commercially by 2030 to meet the EU’s target. The report found that the timeline required to deliver these projects is likely to be a minimum of eight years and timelines beyond 10 years are probable.’

To achieve that would need 25 Hinkley Point C  size nuclear power plants or around 225GW of wind turbines (assuming a 33% load factor).

Realistic?

  • 75GW stations worth across the whole EU in a decade, is undoubtedly possible in principle- consider that when Zaporizhzhia goes back on-line it alone does about 6GW none stop, and had Chenobyl ever had reactors 5 and 6 built, it would have exceeded that by some margin. For very good reasons that long term expansion programme was halted in 1989 and here, further west we do not like that kind of reactor. (radioactive Cumbrian sheep anyone ?)

    Is it realistic to build anything very much in the current mentality, where here we seem unable to organise housing, railway electrification (only been doing that for a little over a century), health, education or a myriad of other stuff, and we are not even at war, no I'd say certainly not, In a decade we might still be arguing the toss about planning consents for tidal lagoons and wind farms.

    However if one considers the climate change problem as something that does requires a war footing, and we may but we do not, yet at least, then of course it is possible. This may occur if whole countries become uninhabitable, and climate induced migration becomes a real thing, rather than a few economic migrants being something to score political points with floating barges etc . My money is on us knowing better by about 2050.
